Re: Looking for recomendations on air pumps

badflash yea I was wondering because it looked like that one you are using. I know they
cost more than a air pump yet they are top of the line for high volume of bubbles in water.

I want to get one some day for a compost tea brewing , already made my own brewer and
like the filter design we came up with (nobody has one like it). However my goal is too be
able to extract microbes from the compost with air aggitation without have the microbes
have to go through a impeller pump. And air is better that way

Re: Looking for recomendations on air pumps

I got a couple of air pumps from Champion Lighting and supply for my 3000 gallon pools. They push a lot of air and are very reliable. I have had them going outdoors for 8 months now and no problems. They are set up for ponds, so head pressure is never a problem. I got the supreme air pump ap 100, but for your application I would try something like the 20 or 40. If you might expand later go bigger and put in a splitter to divert it so your fish aren't in a whirlpool.

Re: Looking for recomendations on air pumps

Hi every one. Ok this is what I have read but am having a little trouble fuguring it out.
1.3 kg O2/kW-h (2.15 lbs./hp hour)

Os consumption can be estimated at about 50% of the feed rate.
in a system fed 4.5kg of feed over an 18-hour period, the estemated oxygen consumtion rate would be about .125kg O2 per hour.
so you need a blower about .275 kw (1/3 hp)

that is from the Southern Regional Aquaculture Center publication number 453
Recirculating Aquaculture tank production systems
A review of component options

I myself am trying to figure out just how much air i will need for a 15'x15'x5' cement tank that is heavely stocked.

Is it right you should feed about 5% of the body weight per day?

The little system at home is really running well but am trying to scale up and set up the first Aquaponics greenhouse in the country. would apreciate any advice any of you vetrents have
thanks yall

Re: Looking for recomendations on air pumps

Don't get too scientific. Err on the side of too much air. One air stone for every 100 gallons running hard will do it. As to how much feed, it depends on the size of the fish. SRAC Publication No. 452 lists recommended feed rates and stocking densities.

I own a Tetra Whisper Air Pump (Non-UL and am greatly happy with it. Have been in function over a year with no problems faced at all. This pump is one of the top 5 air pumps that is not merely inexpensive, it offers outstanding functionality as well.
